' vice illustrated in the accompanying drawings, in which similar letters of reference indicate like parts throughout the several views, and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown the best and most substantial embodiment of my invention, Figure 1 is an elevationof the inner face of the engine hood of an automobile with my device in place thereon; Fig-' ure 2 is an elevation in detail of one of my devices. Figure 3 1s a longitudinal section showing a modification 1n the construction of the invention. Figure 4 is a longitudinal,

section on line H of Figure 2.

The present invention consists of a sheet or curtain of flexible air-proof material A,

having a plurality of transverse stifiening strips G attached thereto, or, if canvas is used for the sheet A, then hems may be sewed therein and a sheet of stiffening material, such as tin, aluminum, celluloid, or other pliant but non-collapsible material,

may be used in said hems to prevent the sag ging and wrinkling of the said sheet A. Clamps D are fastened on said sheet, with portions of each clamp passed through the end portions of each of said stiifeners C. Each of said clamps D consists of a thin strap of metal which has one end thereof fastened by a rivet, or wing portion of the strap bent at right angles to. engage both folds of the sheet A, and through the stifiening material C, thereby holding the said sheet A and the stifi'enersC together. I

To fasten my device in, place on the inner face and covering the louver openings G of the hood H, the free end ofsaid straps D are passed through the louver opening nearest the radiator of an automobile hood,

and the other clamps have" their free ends passed through the louver openings which are respectively contiguous; thenbymoving said sheet ,A longitudinally as to said hood H, the said free ends of each of said straps- D will engage the edge of the louver slot.

The free end ortionsof the said straps D may be bent ack toward the radiator of the car to-engage the edge of the said louver slots and hold the device in" place. I do not confine my invention to the'construction' showmas slight modifications may be nade within the scope of the claims without departingfrom the spirit of the invention. In

Figure 3' I have shown a modification of my lnvention, wherein the stilfening strips 0 are secured to said sheetA by rivets passed through the straps D, sheet A and stiffeners C.
